Bounding scalar operator dimensions in 4D CFT
In an arbitrary unitary 4D CFT we consider a scalar operator phi, and the operator phi(2) defined as the lowest dimension scalar which appears in the OPE phi x phi with a nonzero coefficient. Using
Carving out the space of 4D CFTs
A bstractWe introduce a new numerical algorithm based on semidefinite programming to efficiently compute bounds on operator dimensions, central charges, and OPE coefficients in 4D conformal and $$
Dark Matter benchmark models for early LHC Run-2 Searches: Report of the ATLAS/CMS Dark Matter Forum
This document is the final report of the ATLAS-CMS Dark Matter Forum, a forum organized by the ATLAS and CMS collaborations with the participation of experts on theories of Dark Matter, to select a
Solving the 3D Ising Model with the Conformal Bootstrap
We study the constraints of crossing symmetry and unitarity in general 3D conformal field theories. In doing so we derive new results for conformal blocks appearing in four-point functions of scalars
Bonding and sealing ability of a new self-adhering flowable composite resin in class I restorations
TLDR
The present study demonstrated satisfactory in vitro outcome of the self-adhering flowable composite resin VF when used to restore class I cavities and better marginal sealing ability was visualized in comparison with all-in-one adhesive systems.
Color related to ceramic and zirconia restorations: a review.
TLDR
The unique optical properties of zirconia have introduced new opportunities for achieving superior aesthetics, however further research is required with this material.
Color and opacity variations in three different resin-based composite products after water aging.
TLDR
It can be concluded that for some products, aging of composites in water leads to color instability and opacity variation.
Solving the 3d Ising Model with the Conformal Bootstrap II. $$c$$c-Minimization and Precise Critical Exponents
We use the conformal bootstrap to perform a precision study of the operator spectrum of the critical 3d Ising model. We conjecture that the 3d Ising spectrum minimizes the central charge $$c$$c in
A Randomized Controlled Trial of Endodontically Treated and Restored Premolars
TLDR
Regardless of the restorative procedure, the preservation of at least one coronal wall significantly reduced failure risk (ClinicalTrials.gov number CT01532947).
Bonding to root canal: structural characteristics of the substrate.
TLDR
Evaluating in vitro the dentin morphology in root canals in terms of tubule orientation, density, and increase in surface area after etching revealed variability in tubule density and orientation within different areas of any one sample.
